Starting with NetWare 5 and pure TCP/IP, the Service Location Protocol was adopted as the default,
though optional, discovery mechanism. SLP was chosen because it was the TCP/IP-based protocol
most like SAP in its automatic nature and dynamic refresh capabilities.
For more information, see Section 12.5, “SLP,” on page 113 .
12.4.2 WinSock and Discovery Is NetWare only
There is no WinSock equivalent in the Linux environment. BSDSock provides for transport only,
not name resolution. Therefore, services that leveraged WinSock on NetWare use other service-
discovery mechanisms on OES 2.
12.4.3 UDDI and Discovery
UDDI is an open source, platform-independent registry that lets you provide a discovery service on
the World Wide Web to easily locate, integrate, and manage businesses and services.
For NetWare 6.5, Novell developed a directory-enabled UDDI server for use with the exteNd
TM
J2EE
TM
Application Server. Starting with NetWare 6.5 SP3, the UDDI server component was
removed from the list of products that could be installed.
The Novell UDDI server has been released as open source software and is available for download on
the
Novell Forge Web site (http://forge.novell.com/modules/xfmod/project/
showfiles.php?group_id=1025) .
12.4.4 CIMOM and Discovery
The current OpenWBEM implementation of the Common Information Model Object Manager
(CIMOM) lists SLP as an optional discovery provider. If SLP is to be used with CIMOM, it must be
in compliance with the SLP API specification (RFC 2614). The default discovery vehicle for
CIMOM is the statically configured URI. For more information, see the CIMOM specification at the
Desktop Management Task Force (DMTF) Web site (http://www.dmtf.org) .
12.5 SLP
The OpenSLP services on OES 2 are compatible with NetWare SLP services.
This section discusses the following topics:

12.5.1 Why SLP Is Needed
NetWare: Although many other applications and server types rely on SLP for service discovery,
NetWare services are actually integrated with eDirectory, and if eDirectory is configured correctly,
the services work without SLP. However, SLP is automatically provided on NetWare for other
services that might be installed.
